The adventure trail (Gratweg) between Moosfluh and Villa Cassel has been upgraded this summer. Visitors can continue exploring the world of the UNESCO World Heritage Site at the five modernised stations. The informative, acoustic and playful presentations look at the themes of Wilderness and Civilisation – the Nature Reserve and Alpine Farming – Water Shortage and Reservoirs – the Gratzug and Poor Souls – Nature Conservation and Tourism. Children are encouraged to participate in a fun way.
